#
#  This is my private `install-info' script.
#
#  It inserts INFO-DIR-ENTRY lines of Texinfo `.info' files at the end of
#  an existing `dir.texi' file and recreates the `dir' file either in the
#  directory given by the `--info-dir=DIR' option or in the first matching
#  $INFOPATH directory.  It also creates a backup of the original `dir.texi'
#  file under the name `dir.texi~'.
#
#  *** It cannot insert INFO-DIR-ENTRY lines into an existing `dir' file
#  *** in case no `dir.texi' file exists!
#
#  This script also manages compressed/gzipped Texinfo `*.info' files like
#  `*.info*.Z', `*.info*.z' and `*.info*.gz', also compressed/gzipped `dir'
#  and `dir.texi' files.
#
#  If both the `dir' and `dir.texi' files do not exist, this script will
#  create a new `dir.texi' file and --using it-- a new `dir' file!
#
#  Needs `test', `echo', `head', `eval', `cat', `cd', `cp', `rm', `makeinfo',
#  `set', `gzip' or `compress', `sort', `sed' and `awk' for processing.
#
#  Returns 0 if success.
#  Returns 1 in case an error occurs.
